Fixed BUG#11365: Stored Procedure: Crash on Procedure operation

Browse Source 
Two separate problems. A key buffer was too small in sp.cc for multi-byte
  fields, and the creation and fixing of mysql.proc in the scripts hadn't been
  updated with the correct character sets and collations (like the other
  system tables had).
  Note: No special test case, as the use of utf8 for mysql.proc will make
  any existing crash (if the buffer overrrun wasn't fixed).
